“It’s Only a Theory : Science, Religion and Attitudes Toward Evolution

The controversy over evolution is a long standing one in American politics. The issue is often depicted as a conflict between science and religion. In this paper the effects of confidence in science and confidence in religion on attitudes toward human evolution are estimated. Bivariate analysis shows that confidence in science is positively related to belief in human evolution, while confidence in religion has a negative relationship. However, these effects become very weak when controls for religious beliefs and affiliation are imposed. Religious variables, rather than attitudes toward science, seem to be the main sources of attitudes toward evolution

A length-scale analysis of instabilities in high pressure explosion flames,

Cellular flame structure in high pressure iso-octane-air explosion flames, obtained in the Leeds combustion bomb, was investigated using Schlieren cinematography and OH laser induced fluorescence. High pressure, stoichiometric, iso-octane-air explosion flames were observed to develop a relatively large wavelength cellular structure (3 mm to 7 mm) as a result of the Darrius-Landau hydrodynamic instability. High pressure, rich, iso-octane-air explosion flames ( = 1.4) were observed to develop a cellular structure with two distinct wavelengths present on the flame surface, a large wavelength cellular structure that was comparable with before (3 mm to 7 mm), and a smaller wavelength cellular structure (~ 1 mm). It is suggested that the small wavelength cellularity is caused by the thermal-diffusive instability. It is further suggested that at high pressures, the hydrodynamic instability and the thermal-diffusive instability decouple from each other, resulting in a dual wavelength cellularity

Instabilities and soot formation in high pressure explosion flames

Flame instabilities, cellular structures and soot formed in high pressure, rich, spherically expanding iso-octane-air flames have been studied experimentally using high speed Schlieren cinematography, OH fluorescence, and laser induced incandescence. Cellular structures with two wavelength ranges developed on the flame surface. In rich flames with equivalence ratio ?> 1.8, soot was formed in a honeycomb-like structure behind flame cracks associated with the large wavelength cellular structure

Instabilities and soot formation in spherically expanding, high pressure, rich, iso-octane-air flames

Flame instabilities, cellular structures and soot formed in high pressure, rich, spherically expanding iso-octane-air flames have been studied experimentally using high speed Schlieren cinematography, OH fluorescence, Mie scattering and laser induced incandescence. Cellular structures with two wavelength ranges developed on the flame surface. The larger wavelength cellular structure was produced by the Landau-Darrieus hydrodynamic instability, while the short wavelength cellular structure was produced by the thermal-diffusive instability. Large negative curvature in the short wavelength cusps caused local flame quenching and fracture of the flame surface. In rich flames with equivalence ratio φ > 1.8, soot was formed in a honeycomb-like structure behind flame cracks associated with the large wavelength cellular structure induced by the hydrodynamic instability. The formation of soot precursors through low temperature pyrolysis was suggested as a suitable mechanism for the initiation of soot formation behind the large wavelength flame cracks

Aggregation and the Role of Trusted Third Parties in SME E-Business Engagement: A Regional Policy Issue

YesIt is against the background of low engagement by SMEs in e-business that this paper seeks to highlight the potential importance of aggregation and of the role of trusted third parties in facilitating higher levels of involvement. The paper is based on an ongoing SME e-business research programme and reports on some recent research on SMEs that were using high complexity e-business applications and explores the extent to which the research findings could address the core concern of low engagement. This qualitative case study based research includes analysis of data collected from 13 community intermediaries, acting as trusted third parties. It concludes that the role of community intermediaries appears to be central to the adoption of critical e-aggregation applications provided by service providers. For policymakers, this important role of critical e-aggregation applications in facilitating e-business engagement by SMEs has emerged as part of this research but there is limited evidence of policy initiatives that reflect this

The Potential of Critical E-Applications for Engaging SMEs in E Business: A Provider Perspective

YesAgainst a background of the low engagement of SMEs in e-business this paper investigates the emergence of, and potential for, critical e-applications defined as `an e-business application, promoted by a trusted third party, which engages a significant number of SMEs by addressing an important shared business concern within an aggregation.¿ By a review of secondary data and empirical investigation with service providers and other intermediaries the research shows that such applications can facilitate the e-business engagement of SMEs. There are three key findings, namely: the emergence of aggregation specific e-business applications; the emergence of collaboratively based `one to many¿ business models; and the importance of trusted third parties in the adoption of higher complexity e-business applications by SMEs. Significantly this work takes a deliberately provider perspective and complements the already considerable literature on SME IT adoption from a user and network perspective. In terms of future research the importance of a better conceptual understanding of the impact of complexity on the adoption of IT by SMEs is highlighted

Conducting market research using the internet: The case of Xenon laboratories

The way market research is conducted has changed dramatically over the past 30 years, as a result of both the development of the prevailing view of best practice and the state of technology available to researchers. While it is clear that the World Wide Web (WWW) will increasingly be used as a medium for conducting market research, the full implications of this new channel are not yet fully understood. This paper examines the potential for an Internet-based financial services firm (Xenon Laboratories) to analyse conduct market research using the WWW. The case demonstrates that, by employing a novel approach to market research, Xenon Laboratories is in a unique position to understand the charging structures in its market, the market for international payments using credit or charge cards. In doing so, the paper highlights the opportunity to unobtrusively gather market information from an international group of customers by providing Internet-based value-added services

A knowledge based expert system for moulded part design

In today's competitive market many consumer products are designed with complex curved shapes to meet customers' demands for styling and ergonomics. These styled products are commonly manufactured using moulding processes because they can produce a wide range of freeform shapes at relatively low cost. However, although injection moulding and metal casting allow a great deal of design freedom they also make significant demands on the designer to ensure that parts are designed with due regard for manufacturability. This paper describes a knowledge based moulding advisor that has been developed to provide design for moulding advice to designers during the design process. The main contributions of the research are the development of a hierarchical knowledge representation to allow moulding advice to be generated at different levels of detail and the integration of the expert system with a geometric part description extracted from a Computer Aided Design (CAD) solid model. A demonstrator for the manufacturing advisor has been implemented using the expert system shell CLIPS and integrated with CAD using feature recognition. The moulding advisor is able to generate tailored design for moulding advice for a range of manufacturing processes and materials and evaluate the manufacturability of a designed part at the feature level. The paper provides a case study for a simple moulded test part
